Male progeny of mice were euthanized at the age of 2 mo, and the murine organs were dissected and weighed. (A, B) Body weights in F1 (A, B) in F3. (C, D) Testis weights in F1 (C) and in F3 (D). (E, F) Epididymis weight in F1 (E) and (F) in F3. Testis and epididymis weights were normalized to body weights. F1: n = 23 dose “0,” n = 17 dose “0.6,” n = 42 dose “6”; F3: n = 23, dose “0,” n = 27 dose “0.6,” n = 35 dose “6,” *P < 0.05, Kruskal–Wallis test. All plots on the figure represent averaged values ± SD.
